The biggest thing you'll have to grasp is how to stop your air by forcing your tongue to the roof of your mouth and behind your teeth. It's hard to explain but a good calling cd or dvd could help explain better. I say ticka-ticka or duga-duga or some variation on that. Hope that helps. It's easier show then to type.
Ducks on the water don't do a feed call...just in the air..the tucka tucka tucka call is done by birds going to feed....on the water, ducks chatter.....leave the (a) off..tuck tuck dug dug tick tick goo goo ga ga pick the word or use them all...it will sound like real ducks on the water....
